At present, the demand for labor resources in the world’s construction industry is becoming more and more scarce, especially the construction site of prefabricated buildings, which requires a large number of workers such as hoisting, handling, assembly and connection. The construction circles in Japan, Germany and the United States are working on the development of intelligent assembly mode to greatly reduce the labor resources on the construction site; the way out is to continuously invent and promote robots, automatic devices and intelligent assembly lines, etc., and at the same time innovate and adopt high value-added assembled components And parts, so that the construction site no longer needs a lot of dirty and cumbersome manual labor. Compared with the previous construction mode, this intelligent assembly mode greatly saves human resources, and at the same time can shorten the construction period and improve construction efficiency.
